XCM406 Series
ETR2406-003
High Current High Speed Dual LDO Regulator
■GENERAL DESCRIPTION
The XCM406 series is a high current, dual LDO regulator in an ultra small USP-12B01 package which measures just 2.8mm x
2.8mm. The IC is basically two XC6210 high speed CMOS LDOs which are precise, low noise, high current, regulators
consisting of a voltage reference, an error amplifier, a current limiter and phase compensation circuit plus a driver transistor. The
low ON resistance of the built-in driver transistor means that batteries can be used to a minimal input-output voltage differential
and can therefore be used for a longer time. The series can be used with low ESR ceramic capacitors and output voltages are
selectable in 0.1V increments within a range of 0.8V to 5.0V per channel. The fold-back current limit circuit also operates as the
output current limiter and the output pin protector.
The IC can be placed in stand-by mode via the CE function so that power consumption is greatly reduced.

* A dissipation pad on the reverse side of the package should be electrically isolated.
*1: Electrical potential of the XC6210 series’ dissipation pad should the VSS level.
*2: Electrical potential of the XC6210 series’ dissipation pad should be the VSS level.
Care must be taken for an electrical potential of each dissipation pad so as to enhance mounting strength and heat release when the pad
needs to be connected to the circuit.

■OPERATIONAL EXPLANATION
<Output Voltage Regulator Control>
The voltage, divided by resistors R1 & R2, which are connected to the VOUT pin is compared with the internal reference
voltage by the error amplifier. The P-channel MOSFET connected to the VOUT pin is then driven by the subsequent
output signal. The output voltage at the VOUT pin is controlled and stabilized by negative feedback. The constant
current limit circuit and short circuit protection operate in relation to the level of output current.
<Low ESR Capacitor>
With the XC6210 series regulator, a stable output voltage is achievable even if low ESR capacitors are used, as a phase
compensation circuit is built into the regulator. In order to ensure the effectiveness of the phase compensation, we
suggest that an output capacitor (CL) will be connected as close as possible between the output pin (VOUT) and the VSS
pin. Please use an output capacitor (CL) with a capacitance based on the chart below. We also suggest an input
capacitor (CIN) of 1μF. This should be connected between VIN and VSS in order to stabilize input power source.

≧4.7μF
1.8V ~ 5.0V
≧1.0μF
<Current Limiter, Short-Circuit Protection>
The XC6210 series regulator offers a combination of current limit and short circuit protection by means of a built-in fixed
current limiter circuit and a foldback circuit. When the load current reaches the current limit level, the fixed current
limiter circuit operates and output voltage drops. As a result of this drop in output voltage, the foldback circuit operates,
the output voltage drops further and output current decreases. When the output pin is shorted, a current of about 50mA
flows.
<CE Pin>
The IC's internal regulator circuitry can be shut down via the signal from the CE pin with the XC6210 series. In
shutdown mode, output at the VOUT pin will be pulled down to the VSS level via R1 & R2. Options are available for the
CE pin logic (See the product classification). Note that as the XC6210B types are 'High Active / No Pull-Down',
operations will become unstable with the CE pin open. Although the CE pin is equal to an inverter input with CMOS
hysteresis, with either the pull-up or pull-down options, the CE pin input current will increase when the IC is in operation.
We suggest that you use this IC with either a VIN voltage or a VSS voltage input at the CE pin. If this IC is used with the
correct specifications for the CE pin, the IC will operate normally. However, supply current may increase as a result of
through current in the IC's internal circuitry if a voltage other than VIN or VSS is applied.
■NOTES ON USE
1. Please use this IC within the stated absolute maximum ratings. The IC is liable to malfunction should the ratings be
exceeded.
2. Where wiring impedance is high, operations may become unstable due to noise and/or phase lag depending on
output current. Please strengthen VIN and VSS wiring in particular.
3. Please wire the input capacitor (CIN) and the output capacitor (CL) as close to the IC as possible. When rapid input fluctuation or
load fluctuation occurs, please increase the capacitor value such as CIN or CL to stabilize the operation.
